Beijing Olympic Tower

The Beijing Olympic Tower (pinyin: Běijīng Àolínpǐkè Tǎ) is located on Kehui South Road, part of the Olympic Green in the Chaoyang District of Beijing, China. Construction began in 2011, three years after the 2008 Summer Olympics; it was completed in 2014, and opened on August 8, 2015. It is used strictly for observation; there is no provision for offices or apartments. The design was by a Chinese firm, China Architecture Design & Research Group; a Shenzhen architect alleged that the architects at the firm had plagiarized an award-winning earlier design of his. At 258 metres (846 ft) in height it is the second tallest tower in the city after the Central Radio & TV Tower, and the fourth-tallest structure in the city. Its design, with four smaller circular floors at different heights and positions below a larger top floor, is meant to echo the Olympic rings. The overall design was inspired by blades of grass; however it has also been likened to "huge nails".
